EEG (Electro-Encephalogram) helps measuring and recording brain’s electrical activity. It’s used to diagnose epilepsy, problems of consciousness or dementia, sleep disorders such as narcolepsy, etc. It aids in recording the brain’s electrical activity on paper in the form of wavy lines or over the screen.

EMG (Electromyography) is for patients with symptoms of muscle weakness, stiffness, or atrophy. Often, this testing is done for diagnosing muscle and nerve disorders such as myasthenia gravis, muscular dystrophy, myotonia, neuropathies, and myopathies.
